--- title: "PVE8 上启用 12 代 Intel CPU 核显 SR-IOV" description: "拯救我的 Galgame 和追番体验～" date: "2023-08-06" tags: - "折腾" - "PVE" canonical: "https://xxxuuu.me/post/pve8-intel-sr-iov" --- ## 背景 前段时间买了台 MiniPC 装 PVE 作为 Homelab，打算作为媒体服务器 + NAS + 学习使用 ~（虽然最后主要是用来装 Windows 虚拟机玩 Galgame）~ 机子的 U 是 12 代的 i3-N305，买的时候 PVE8 还没发布，装的是 PVE7，5.x 的内核，对 12 代 U 还没有很完善的支持，核显无法使用。这就导致在 Jellyfin 看番只能软解，以及玩 Galgame 时压力都在 CPU 上，全程 CPU 100%，体验说不上好 最近发现 PVE8 发布了，升级到了 6.2 的内核，于是赶紧折腾一下。升级过程网上很多文章，这里略，无非就是配置下镜像源然后 `apt update & apt dist-upgrade` ## 开启核显 SR-IOV SR-IOV 是一种硬件虚拟化技术，简单来说，能将物理 PCIe 设备虚拟成多个虚拟设备，在网卡上被广泛使用。Intel Core CPU 在 11 代后支持了该技术用于 GPU 虚拟化，替换了过去的 GVT-g（[Intel 产品 GPU 虚拟化技术列表](https://www.intel.cn/content/www/cn/zh/support/articles/000093216/graphics.html)） 开启 SR-IOV 主要用到这个驱动程序：[i915-sriov-dkms](https://github.com/strongtz/i915-sriov-dkms)，能够创建最多 7 个 VF（可以简单理解为 vGPU） 按着文档里「PVE Host Installation Steps (Tested Kernel 6.1 and 6.2)」这步做即可。在 `update-grub` 和 `update-initramfs -u` 后多执行一句 `pve-efiboot-tool refresh` 但我这里遇到一个问题，重启后查看 `dmesg | grep i915` 有这样两条日志 ```plain i915: unknown parameter 'max_vfs' ignored .... i915 0000:00:02.0: driver does not support SR-IOV configuration via sysfs ``` 看了[这个 issue](https://github.com/strongtz/i915-sriov-dkms/issues/53) 后，尝试重装。删除了原来的 dkms 模块，修改 `dkms.conf` 里的 `PACKAGE_NAME` 为 6.2（和内核版本匹配），然后 install 时加上 `--force` 重新走遍安装流程 这回正常了，上面两条日志没有了，也显示成功启用 VF，`lspci | grep VGA` 能看到多出来 7 个 GPU 设备，可以将其挂载到 LXC 或虚拟机中（00.02.0 那个物理 GPU / PF 不应该被使用）

进入 LXC 容器安装驱动 ```bash $ apt update && apt install intel-media-va-driver-non-free vainfo ``` 如果 LXC 内也使用了容器，例如我在 LXC 内装了 Docker 部署 Jellyfin，则容器内也要有驱动，并把设备挂载进去 ```bash $ docker run ... \ ... \ --device /dev/dri:/dev/dri \ ... ``` 然后 Jellyfin 容器内就可以找到对应设备，启用硬件加速即可

## 总结 核心就两步： 1. 在 host（PVE）上安装驱动模块，开启 SR-IOV 2. 配置虚拟机 or LXC 挂载 vGPU，并在里面安装驱动 有了 GPU 后体验好了很多，无论是 Windows 玩 Galgame 还是 Jellyfin 追番硬解，CPU 压力基本不超 5%，十分流畅，释放了本就不强的 CPU 算力。而且相比独占的直通物理 GPU，SR-IOV 虚拟出来的多个 vGPU 能分给多台虚拟机使用，打造完美 Homelab ## 更新 2024/09/25 更新 我将 PVE 版本升级到了 8.2.7，内核版本为 6.8.12。升级后因为内核版本变更，原来的修改就会失效，这里更新一下如何处理 首先需要卸载掉旧的模块 ```bash $ dkms status i915-sriov-dkms/6.2, 6.2.16-6-pve, x86_64: installed $ dkms remove i915-sriov-dkms/6.2 --all Module i915-sriov-dkms-6.2 for kernel 6.2.16-6-pve (x86_64). Before uninstall, this module version was ACTIVE on this kernel. i915.ko: - Uninstallation - Deleting from: /lib/modules/6.2.16-6-pve/updates/dkms/ - Original module - No original module was found for this module on this kernel. - Use the dkms install command to reinstall any previous module version. depmod... Deleting module i915-sriov-dkms-6.2 completely from the DKMS tree. ``` 然后重新走一遍[仓库](https://github.com/strongtz/i915-sriov-dkms)中安装驱动流程，这里同样按照对应内核版本的指南（PVE Host Installation Steps (Tested Kernel 6.5 and 6.8)）操作即可 操作的时候注意替换相关命令为自己的内核版本，免得出现问题。例如 `apt install proxmox-headers-6.8.8-2-pve proxmox-kernel-6.8.8-2-pve` 我这里改成 `apt install proxmox-headers-6.8.12-2-pve proxmox-kernel-6.8.12-2-pve` 之前已经修改过 GRUB 等配置，因此重新安装完驱动（`dkms install ...`）后就可以直接重启系统生效，LXC 和 VM 也不必重新配置
